安装
npm install vxe-pc-ui@4.3.90 vxe-table@4.11.0
// ...
import VxeUI from 'vxe-pc-ui'
import 'vxe-pc-ui/lib/style.css'
import VxeUITable from 'vxe-table'
import 'vxe-table/lib/style.css'
// ...
createApp(App).use(VxeUI).use(VxeUITable).mount('#app')
// ...
默认模式
默认是固定模式，拖动滚动也会保持渲染内容居中状态，不会多次渲染

内嵌模式
内嵌模式的原理由多个 table 渲染完成，所以会多次渲染，使用时可以通过判断标识来处理多次渲染问题
